To all whom it may concern:

Be it known that we, FRANK HEDLEY and JAMES S. DOYLE, both citizens ofthe United States, and residents, respectively, of Yonhers and MountVernon, in the county of Westchester and State of New York, have made acertain new and useful Invention in Street-Sweeping Machines, of whichthe following is a specification.

This invention relates to street sweeping machines. The object of theinvention is to provide an apparatus of the nature referred to which issimple in construction, economical to 5 manufacture, easy to operate,and eflicient in operation.

'A further object is to provide a street sweeping apparatus wherein isemployed a rotary sweeper carried by a frame in such 2o manner that saidsweeper may be swung laterally and horizontally from one side to theother of the frame on which it is mounted.

Other objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination,location and relative arrangements of parts, all as will be more fullyhereinafter set forth, as shown in the accompanying drawings, andfinally so pointed out in the appended claims.

In the drawings: Figure 1 is a view in 'top plan of a sweeping apparatusembodying the principles of our invention, positions of the rotarysweeper on opposite sides of the carrier frame being indicated in dottedlines. ,Fig. 2 isa view in side elevation of the same. Fig. 3 is a viewin horizontal section on the line 3, 3, Fig. 2, looking in the directionof the arrows, parts broken ofii.

40 It is a common practice to employ rotary sweepers mounted upon frameswhich arepropelled along the streets to be swept, or'

along track rails of street car systems, the sweeper being suspendedunderneath the as carrier frame and ordinarily disposed 1n a generallytransverse position across thev frame and in a transverse direction tothe line of travel or propulsion of the frame. In the operation of suchsweepers, so arranged, a comparatively limited area is cov ered, andwhere such a machine is employed to clean snowor dirt along the. tracksof a street car system, or instance, the result is to le vethe. snowordirt swept from-t e .65; patent he iyeepeapi edapin 1ine;;para1.--.

lel and closely adjacent to the trackrails, making it diflicult andinconvenient for pas sengers to board or alight from cars operatingalong the track system. Moreover if the sweeper is arranged to extendbeyond the sides of the carrier frame in which it is mounted, on oneside or the other thereof, the vehicle which carries the sweeper must bturned around at the end of the line in order to enable the sweeper tooperate at'the opposite side of the track on the return trip,

and in many instances it is inconvenient or undesirable to turn thevehicle.

It is among the special purposes of our present. invention to provide acarrier de signed to operate on the track rails of a street car systemand to mount thereon a rotary sweeper in such manner as to permit thesweeper to be rocked'or swung into position to project or extend beyondeither side of the carrier without disturbing or interfering with thedrive gearing through which the rotary brush is operated, therebyenabling the apparatus to clearaway snow, rubbish or the like from theimmediate vicinity of thetrack rails, the brush open ating on one sideof its carrier vehicle while said vehicle is moving in one direction andon the other side while moving in the opposite direction.

While the principles of our invention may be carried out in manyspecifically different embodiments, without departure from the spiritand scope of the invention as defined in the claims, we will describeone arrangement as illustrative of the principles involved and which wehave found to be simple and efficient.

In the construction shown A. designates a vehicle which, in the instanceshown is mounted on supporting wheels 13. If desired, thoughnot'neoessarily, the supporting wheels B maybe truck wheels and may operate along the track rails C of a street rail way system, the trucksbeing located at the ends of the vehicle.

Intermediate its ends the body portion D of the vehicle" A is elevatedor arched, as clearly shown in Fig. 2, leaving the end portions E, withan open space F, between them. Extending a short distance into the spaceF, from the base of one of the end compartmentsor portions E is asupport G, in which and in the overhanging bodvpart Dis journaled' a rtal h ft M nted upon shaft H to rock therewith is a frame .J, portions ofwhich extend on opposite sides of the shaft H. In one portion of 'frameJ is journaled a horizontal shaft K tated. The frame J. and the motorand sweeper devices and intermediate gearing are located and operate inthe space F between the ends E of the vehicle carrier A. In order toenable the sweeper L to operate at one side or the other of the vehicle,as indicated in dotted lines in Fig. 1 it is only necessary to rock theframe J laterally and horizontally about the vertical axis of shaft H,in one direction or the other, as may be desired. This may beaccomplished in many different ways, as, for instance,'by attachingframe J to shaft H so as to rock therewith, and providingsome means forrocking said shaft H. A simple arrangementis shown wherein shaft H isrocked axially by means of a small auxiliary motor P, through suitablegearing R, S.

In operation the sweeper L is liable to encounter rough or unevensurfaces, stones, cobbles or the like. In order to avoid damage orinjury it is desirable to provide means whereby in such event, thesweeper may easily ride over or clear the obstruction. vTo this end wepropose to mount the shaft H for vertical longitudinal movement througha desirable range.v To permit such vertical movement of shaft H one orthe other of the intermeshing gears S. B. may be provided with elongatedteeth. By this arrangement it will be readily seen that when the sweeperL encounters an obstruction in its path the entire frame J can risesufiiciently to permit the sweeper to pass or ride over theobstruction,without interfering with the sweeper drive gearing or the gear ing whichrocks the frame J laterally. At the same time the weight of the frame "Jand of the parts carriedthereby is imposed on the sweeper L toefficiently hold the same to its work. The motor M serves as a counter.

weight for the portion J of the frame which carries'the brush L.

It will be readily seen that the provision of the open space Fintermediate the wheei or truck supported ends of the vehicle affords amost convenient arrangement to permit the sweeper to be swung laterallyand horizontally so as to project or extend beyond either side of thevehicle, and at any desired angle. Ordinarily, and in order to deflectthe sweepings away from the vehicle, or, for instance, from thetrackrails, the sweeper will be somewhat inclined outwardly andrearwardly with reference to the direction of travel, and consequentlyit lsnnnecessary to turn the vehicle around when the Vehicle reaches theend of a line. All that is necessary to do to permit the sweeper tooperate on the opposite side of the vehicle when the latter proceeds inthe opposite direction on its return trip without turning around at theend of the trip is to swing the frame J to the other side of the vehicleand in similar outward and rearwardly inclinedrotation with respect tothe new line of travel of thevehicle. And this action does not evenrequire a reversal of the motor M. While the car is being run alongstreets or tracks which do not require the operation of the sweeper andalso while passing other vehicles occupying the street when the sweeperis in operation, the brush and its supporting frame will be swung intoposition underneath the car and therefore will not interfere with otherstreet traffic.

Having now set forth the objects and nature of our invention and aconstruction embodying the principles thereof, what .we claim as new anduseful and of our own invention, and desire to secure by Letters Patentis,
